2Increased branching independent of strigolactone in cytokinin oxidase 2-overexpressing tomato is mediated by reduced auxin transport显示文摘Tomato production is influenced by shoot branching,which is controlled by different hormones.Here we produced tomato plants overexpressing the cytokinin-deactivating gene CYTOKININ OXYDASE 2(CKX2).CKX2-overexpressing(CKX2-OE)plants showed an excessive growth of axillary shoots,the opposite phenotype expected for plants with reduced cytokinin content,as evidenced by LC-MS analysis and ARR5-GUS staining.The TCP transcription factor SlBRC1b was downregulated in the axillary buds of CKX2-OE and its excessive branching was dependent on a functional version of the GRAS-family gene LATERAL SUPPRESSOR(LS).Grafting experiments indicated that increased branching in CKX2-OE plants is unlikely to be mediated by root-derived signals.Crossing CKX2-OE plants with transgenic antisense plants for the strigolactone biosynthesis gene CAROTENOID CLEAVAGE DIOXYGENASE(CCD7-AS)produced an additive phenotype,indicating independent effects of cytokinin and strigolactones on increased branching.On the other hand,CKX2-OE plants showed reduced polar auxin transport and their bud outgrowth was reduced when combined with auxin mutants.Accordingly,CKX2-OE basal buds did not respond to auxin applied in the decapitated apex.Our results suggest that tomato shoot branching depends on a fine-tuning of different hormonal balances and that perturbations in the auxin status could compensate for the reduced cytokinin levels in CKX2-OE plants.Lilian Ellen Pino Joni E.Lima Mateus H.Vicente Ariadne F.L.de Sá Francisco Pérez-Alfocea Alfonso Albacete Juliana L.Costa TomášWerner Thomas Schmülling Luciano Freschi Antonio Figueira Agustin Zsögön Lázaro E.P.Peres 2022Molecular Horticulture2022,2,1:0
